Gloss is not something you add. It is what is left when nothing is wrong with the surface.
People assume a high-gloss finish comes from a final shiny coat. It does not - a shiny coat over an uneven surface simply gives you a shiny uneven surface, and on a dark colour that is far more obvious than a matt one, because a dark gloss works as a mirror and mirrors magnify every fault they carry.
So our master Indian artisans build the blue in many thin coats and cut each one back flat before the next goes on. Every cycle removes the high points and fills the low ones a little more. The colour is being deepened and the surface is being levelled at the same time, and the second matters more than the first.
The test is not to look at the door. It is to look at what the door reflects. Find a straight edge in the room - a door frame, a window reveal - and let your eye travel down its reflection in the lacquer. If the reflected line stays straight the whole way down, the surface is flat. If it bends, waves or thickens anywhere, there is a hollow there, and no amount of polishing will hide it.
You can run that test on this wardrobe. That is the point of doing it properly.
